DBEDGE CAN.

Application led December 4, 1922. Serial No. 604,756.

My present invention relates to dredge top cans and, while lit is applicable to cans adapted for a wide variety of uses, ithas particular advantages in connection with containers for bath and cleansing powder, and the like.

A principal object of the invention 1s the provision of a can of this type in which the dredging openings are normally closcdand' may be opened only by a positive action, means being provided to automatically close the openings after the can is used.

Another object is the provision of a dredging can having the foregoing characteristics which may be readily opened by one hand by the mere exertion of slight pressure upon a conveniently positioned protruding part.

The invention also'has for an object the provision of simple spring means for automatically controlling the position ofthe closing member which may be economically provided and assembled, without adding materially to the cost of the can.

Other objects and advantages of the 1n- Vention will be apparent as it is better understood from the following description, which, taken in connectionwith the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings,

Figure 1 is a perspective view of a dredge can in which my invention is embodied;

Fig. 2 is a top plan View thereof, partly broken away and with certain of the interior parts lshown in dotted lines to illustrate the f dredge top construction;

Fig. 3 is a section through the upper part of the can, taken longitudinally of the slide and spring; and

F ig. 4 is a section taken transversely of said parts.

. The can illustrated in the drawings comprises a fibre body v11, to which is secured. in any'preferred manner, a sheet metal bottom end 12 and which is provided, at its upper end, with a dredge top structure, to be described in detail.

An inner top member 13 is secured to the fibre body wall by means of an inner vertical wall portion 14 and a flange 415, which is turned over the edge of the body wall and embedded therein, as shown at 16. Said top member is formed with a channel 17 defined by the wall portion 14, and an inner upstanding wall 18, which terminates in an elevated central part 19, which, in the present instance,

is disposed slightly above the top of the body. Said-raised center 19 is formed with a transverse channel 2l, which serves as a guideway for a dredge slide 22. The inner top is provided with perforations at 23, disposed in the channel 21, and the slide 22 has perforations 24 adapted to be brought into registra tion with the pcri'orations, or openings, 23. Said slide 22 has a down-turned inner end lug or flange 25 adapted to engage the upper part of the wall 18 to limit the outward sliding movement, and the outer end of said slide is turned down to provide a rounded lingerpiece and stop 26.

A smooth outer top or cap 27 is secured over the top 13, said outer top being held in place by a rounded flange 28 cngagingthe body wall beneath the flange 15.l Said top 27 is cut-away to provide an opening 29, through which the slide 22 extends and it will be noted that said slide is held by said top 27 in the guideway between the covers.

In order that the sitter openings may be normally closed I provide a spring 3l,` one end 32 of which is turned to horizontal position and inserted in a groove 33 formed in the top member 13, the other end 34 oli' said spring being also bent to horizontal position and inserted in a retaining aperture formed in a cut-out portion 35 'ofthe slide 22. The material at the bottom of the groove is Slotted at 33 to permit insertion of said spring 31. i

The top 27 is provided with perforations 36, corresponding to the perfor-ations 23 and 24 in the inner top and slide, respectively. 1t will be seen that the tension of the spring 31 'normally holds the slide 22 in its outer position with the end26 protruding from the covers and, in this position the perfor-ations 24 are out of alignment with thoseof the inner and outer covers. In order to uncover the sifter openings, it is merely necessary to exert slightpressure on the end 26 of the slide, forcing the same to its inner osition with the perforations therein Ain alignment with those'of the covers. This opening operation may, of course, be readily performed by the hand which holds the can and the slide is held in inward position while the contents are being sifted out. Upon release of said slide, the spring 31 forces it to the outward posi tion, closing the sifter openings and, in this manner, the latter will alwaysbe closed except when the can is in use.

Aterior of t The parts employed in this construction are relatively simple and permit economical manufacture and the assembled container presents a plain and pleasing appearance. The benefits of a package which will be automatically closed after use and yet is capable of being easily opened, will be manifest to those familiar with the uses to which such containers are put.

It is though that the invention and many of its attendant advan'ages will be undersood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts, without departing from the spirit and scope of the invention, or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred einbodiment thereof.
